OIL BURNER. I

' Application. filed November 6,: 1924. Serial No. 748,167.

character. in which the fuel oil is vaporized.

and intimately intermixed with a maximum amount of air to obtain efficient combustion at a minimum expenditure of oil.

A further object is to provide a burner consisting of but few parts which may be manufactured and assembled at small cost.

Another object is to form and arrange the parts in'such manner that there will be no small orifices, or restricted passageways to become clogged with carbon or other products of combustion.

In order that the invention may be fully understood, reference will now be had to the accompanying drawing, in which:

Fig. 1 is a side elevation partly in section of the burner.

Fig. 2 is a cross section on lineII-II of Fig. 1.

Fig. 3 is a modified form of a portion of the burner.

Referring now more particularly to Figs. 1 and 2, 3 designates a retort which may be made in different forms to fit difi'erent shaped fire boxes in stoves, furnaces, etc. Said retort consists, preferably, of one casting having a centrally-disposed neck 4 rising from a trough 6 near the base 8 of the retort. Fuel oil is supplied to the retort 3 through a pipe line .10, provided with a suitable valve 12 whereby the flow of oil to the retort may be regulated as desired.

14 designates a deflector arranged at the upper end of the neck 4. Said deflector con sists of a semispherical head 16 and ribs 18 which latter are integral with and support the former and in turn are provided with shoulders 20, which rest upon the upper end of the neck 4. The neck 4 and the ribs 18 form passageways 22 through which the vaporized fuel escapes from the retort 3 into a primary mixing chamber 24.

The primary mixing chamber 24 is formed by a dome 26 provided with spacing lugs 28 which rest upon the head 16. As shown by Fig. 1, the dome 26 encloses the head 16 and the upper portion of the neck but is of greater diameter toleave thejmixing chamber: 24 into which the vaporized fuel flows. from the retort 3 through the passageways 22. An air port'30 is formed in the, upper portion of the dome 26 for the admission of air to the mixing chamber 24 where it combines with the vaporized fuel and forms a rich, combustible mixture.

32 designates a hood extending downwardly over the dome 26 and to within a short distance of the trough 6. Said hood .32 is heldin concentric relation with the neck "4 and the dome 26 by spacing lugs 33,

projecting from 'the retort 3. The hood 32.

is of greater diameter than the dome 26 to form a supplemental mixing chamber 34,

which is supplied with a. relatively large volume of air through a primary air tube 36 communicating at one end with the upper portion of the hood 32 and at its opposite end with a suitable blower 38. Ad-

ditional air is supplied to the primary tube 36 through a supplemental air tube 40, which latter is connected to the formerby suitable means such as a T-co-upling 42.

In practice the burner 32 may be started by allowing oil to flowinto the retort 3 and overflow 'into the trough 6 where it is ignited. The flame thus produced heats the retort. 3 and causes vaporization of the oil therein. As the vapor escapes through the passageways 22 it initially combines with the air admitted to the primary mixing.

chamber 24 where it takes up more air sup plied by the tube 36 and ignites as it passes outwardly between the lower end of-the hood 32 and trough 6. The continuous flame thus produced continues to heat the retort 3 and vaporizes the oil admitted thereto and also heats the air flowing through the chambers 24 and 34, so that there willbe no danger of such airv coolficient mixture is obtained and the air fiow- 4 ing through the port 30- sweeps away any carbon or other deposits which might otherwise lodge in and clog the chamber 24.

In the modified form disclosed byFig. 3, a cage-like deflector 14 is substituted for the deflector 14. Said deflector l4 has a ing separated from passageways 22 in the lower portion of the deflector by a partition 52. The lower end of the deflector 14 1s reduced to fit into the upper end of the neck l and has a shoulder 20 whereby said deflector is supported upon said neck.

While I have shown two forms'of the 1n- VBlitiOD- I reserve the right to make such other changesin tIierOnStruCtiOn, combinati'on'and arrangement of partsas properly fall within the spirit and scope of the invention'as'claimed I I Iavi'ng-t hu's deseribed my invention, what I claim and desire to seizure by LettersiPatentgds 1. Ina burner of the character described,

a retort terminating at its upper end in reduced neck, a defieetor at the upper'end of saidneck, a dome extending over said deflector and provided: with an air port, and aheed extending over said dome and provided with an air inlet.-
